编辑：我尝试从-clean 开始，但没有解决。

【问题讨论】：

你可以试试这个。打开命令窗口或 shell。转到包含 Eclipse 二进制文件的目录。运行eclipse -clean。
重要如果您将项目保存在工作区文件夹中：立即备份

见How to run eclipse in clean mode? and what happens if we do so?

http://aglazkov.wordpress.com/2010/07/18/one-way-to-restore-eclipse-workspace/

http://breathingtech.com/2009/how-to-reset-workspace-in-eclipse/

打开您的任务管理器->右键单击javaw.exe进程->选择结束进程树（这将结束您计算机上运行的所有java运行时进程）。

然后转到您的 Eclipse 文件夹 –> configuration.settings 并删除 org.eclipse.ui.ide.prefs 文件。重新启动 Eclipse 并尝试再次打开您的工作区。这对我有用 :) 请注意，删除此文件会导致重置您的工作区历史记录，因此在启动 Eclipse 时您需要手动浏览到您的工作区位置。

删除工作区文件夹或重命名它

【解决方案2】：

我遇到了类似的崩溃，使用 -clean 选项启动 Eclipse 并没有帮助。我最终删除了.metadata\.plugins\org.eclipse.e4.workbench 文件，解决了这个问题。

【讨论】：

太棒了。我遇到了完全相同的问题，我可以通过删除.metadata/.plugins/org.eclipse.e4.workbench 来解决它。谢谢。
删除 org.eclipse.e4.workbench 工作，谢谢，对我来说，这是在创建第一个使用 Android 4.4 的项目后重新启动后发生的。
首次使用 Android 4.4 后出现同样的问题并在此处修复。
也为我工作。只是想补充一点，我在堆栈跟踪上遇到了与 OP 不同的崩溃（这是一个死锁），并且仍然删除该文件夹中的文件为我解决了这个问题。
有效。但是这个文件是什么？我们会失去什么？

【解决方案3】：

我的机器很慢，我尝试关闭 eclipse 。经过几次尝试，日食关闭了。重启机器后，eclipse没有打开，显示多个错误。

我删除了.\metadata\.plugins\org.eclipse.jdt.ui\variablesAndContainers.data file and .\metadata\.plugins\org.eclipse.e4.workbench\workbench.xmi 文件。

之后 eclipse 开始工作了。

【讨论】：

【解决方案4】：

没错。您可以通过删除或重命名工作台目录中的此文件夹来解决此问题 - .metadata/.plugins/org.eclipse.e4.workbench 到 .metadata/.plugins/org.eclipse。 e4.workbench.temp .

【讨论】：

【解决方案5】：

对于 windows 用户，此文件夹位于工作区 C:\Users\elminson\workspace\\.metadata\\.plugins

【讨论】：

【解决方案6】：

转到您的 Workspace/.metadata/.plugins 并删除其中的所有内容。 Eclipse 将启动并重新生成文件夹和文件。

【讨论】：

【解决方案7】：

以上几点都对我不起作用后，我只是在任务管理器中检查了 RAM 使用情况。令我震惊的是，我发现，在我拥有的 2 GB RAM 中，我只剩下 100 MB。 Eclipse 需要 1 GB 的空间。我杀死了所有其他不需要的应用程序，然后重新运行了 eclipse。

它很简单:-)

现在，当我运行 eclipse 时，我运行它时没有任何 不需要的、RAM消耗应用程序
